GREEN.L 49mm Infrared Filter, 49mm IR 850nm (R85) Filter for Camera Lens

I got this filter to try my hand at infrared black-and-white film photography because it was much less expensive than other brands, and I didn't want to break the bank before I had a chance to see if IR photography would be something I'd want to do repeatedly. After researching the different wavelengths of filters, I settled on the 760nm option for its higher contrast and overall more pronounced IR effect with IR-sensitive film (Rollei IR400).The results were incredible, especially for my first foray into such a niche kind of landscape photography, and this filter transmitted sharp, punchy images. I don't think I'll need to get any other IR filter, as this one seems perfect.I'm glad I took the plunge!Tip: This filter requires an additional 10 stops of exposure over unfiltered meter readings. So, if metering without the filter on the lens or light meter, and you get, say, 1/1000 second shutter speed, you'll actually need to use 1 second instead. Not a big deal when shooting landscapes, though.

I see a bunch of people complaining that these don't work, but it looks like they are all using them incorrectly. You must have a camera that has been modified to remove the IR cut filter in front of the sensor - usually called a full spectrum modification.. Almost all cameras BLOCK infrared light in their stock form, and if they do let any in, you need a really long exposure. I have a modified Canon 5D, and these filters work great and do exactly what they are supposed to when used correctly. The 950nm filter is pitch black, letting almost no visible light through, but on my modified camera with correct white balance settings, takes great black and white infrared photos, clearly showing infrared light, without any long exposure at all. All for way way less than the usual price for these types of filters. As for quality, I've not noticed any obvious optical flaws with these when used with Infrared.

Well-made and great packaging. The red hue seems a bit off from more expensive brands, but the clarity and quality of glass seems well done. Great budget option!

I've tested the GREEN 52mm 850nm filer I received compared to a B+W 093. The 093 is a 830nm filter (despite its unusual name) while the GREEN filter is listed as 850nm cut. I don't have a spectrometer to measure the GREEN filter curve, but I could compare with the B+W which is a known quantity of high quality. I shot both filters both on a 590nm converted Nikon Z7 and a stock Z7.First, there is no appreciable visible light leakage. I shot both the GREEN and B+W on my stock Z7 at F/2 30" and ISO 25600 of a daylight scene. Both filters produced the same level of exposure and clearly the filters both block visible light strongly while the Z7 blocks IR strongly.Second, the level of exposure in IR is as expected. Shooting both filters on my modified 590nm Z7 the required exposure on the GREEN was half a stop more than the B+W 093 (i.e. the GREEN was blocking more light). This is again about as expected since the GREEN does cut at a longer wavelength and thus allows less light through.It is not possible for me to test how sharp the cutoff is for the GREEN in comparison to the B+W, but it is clearly do the job it is meant to and any difference is not affecting IR exposure in any way I can detect.In addition I compared both filters as far as reflections go. The B+W 093 does not advertise any fancy coatings at reflections for the two filters were the same. I checked reflections in IR - remember that AR coatings only work over a certain wavelength range and so for an IR filter reflections you see with your eyes aren't meaningful!I also purchased 67mm and 82mm versions of the filter. I did not test them as extensively but from use they appear identical in performance.In short, at least the ones I got do exactly the job they advertise - they filter at about 850nm and block all visible light just as well as a much higher end filter.

I’m a retired commercial photographer of 55 years and realize filter quality is very important. Putting a bad quality filter on a good lens degrades the image quality.I recently had one of my cameras converted to full spectrum IR and wanted a selection of IR cutoff filters. Name brand manufacturers filters were limited as to size and the prices were high. I ran across these on Amazon and the price was good so I thought for the price I’d give them a try.So far I’m very pleased with my choice. The quality seems very good and the cutoff point seems to be exactly as the manufacturer states. I have no issues with quality or performance at this point.

This is a decent 720nm filter, but doesn't compare with the filters available from Kolari. Whereas the Kolari filter truly removes ALL visible light, this "Green.L" filter still lets some of it sneak through. I have proven this to myself with a careful test involving a good quality UV/IR block filter.While not quite the "cutoff" that the Kolari is, this filter is still usable since the amount of visible light is several stops down.I suppose you get what you pay for. This filter runs about $30 compared with Kolari's $114.

I am so super-pleased with this item it worked far better than I had imagined with my "cell phone camera lens". I've attached an untouched image which I can reimagine through any photo editor. I have worked with actual IR film on the past.. I can rework to hi-contrast B&W (my goal) or any number of other creative effects. I simply luv the IR effect on the foliage leaves! -This is going to be fun!
